Spectral-domain optical coherence tomography findings in Alström syndrome

This study reports on OCT findings in a large group of patients with Alström syndrome. We document a panretinal gradual progression of retinal changes, which are often mild during the first years of life. Previously unreported observations include intraretinal opacities, optic nerve drusen, and foveal contour abnormalities. Morphological retinal changes demonstrated by SD-OCT may help in understanding the pathophysiology of the disease and defining strategies for treatment such as gene therapy.
